Coax Feedline — Genuine Times Microwave & Heliax

Coax Feedline

The Part of the Station Nobody Looks At.

Coax loses power as heat, and the loss grows with length and frequency — on transmit and on every weak signal coming back. Gary, KC4ES, changed nothing but his cable, RG8X to LMR-400, and called it the difference between a good antenna and a great one. Genuine Times Microwave LMR and Heliax, cut to length, terminated, and sealed. See what your cable costs you →

Which Cable, Which Length

Length: measure radio to feedpoint, then add about 15% for routing and a service loop. Pick the next length up.

LMR-400: the sweet spot at HF for most stations.

LMR-600: earns its premium past 100 feet, at legal limit, or buried.

With an antenna in the same cart: 10% off automatically, and it ships free.

On its own: $9 shipping up to 10 lb, $19 to 20 lb.
